How Many Watts Per Square Foot For Lighting

One of the most important decisions you’ll make when designing a new building or remodeling an old one is deciding on the energy usage. You need to think about everything from lighting needs to appliances used, and even the size of rooms can affect your energy usage. This blog post will give you some tips on estimating how much electricity you’ll need for lighted areas in your home or business.

Square Footage

A square foot is a measurement of space, not volume. It’s important to understand how much energy your light bulb uses because the number of watts per square foot will vary depending on how large your area is. For example, residential LED lights use around 20-25 watts per square foot while commercial LED lights use only 10-15 watts per square foot.

Color Tone

Color Temperature

Color temperature is measured in Kelvins (K) and describes the color of light.

The higher the color temperature, the whiter and cooler it will appear to be.

For example, a warm incandescent light bulb has a color temperature around 2700K while an overcast day has a color temperature of about 5500K.

Other Considerations

There are a few other things to consider when choosing your wattage needs. First, think about the type of light you want and/or need. Is it going to be used for task lighting? Do you need a lot of ambient lighting? Are there many dark corners or areas where daylight doesn’t reach well?

Next, think about what kind of fixtures you have to work with (or can afford). Can you put in new track lighting in the kitchen? Will an outdoor floodlight illuminate enough for your driveway area? Will fluorescent lights provide enough bright white light for your office space without making everyone feel like they’re back in school again on Monday morning after the weekend’s sleepaway camp event left them slightly less than refreshed from Saturday night’s excitement. It’s also worth noting that while LEDs are more efficient than incandescent bulbs, they still generate heat so make sure that if choosing this option, make sure there’s enough ventilation around each fixture so as not to cause damage over time due to overheating.”

What Is Square Footage?

When you hear someone say they’re going to add more lighting to a room, it can be confusing as to how much this means. Are we talking about watts per square foot? What exactly is “watts per square foot”?

In order to understand watts per square foot, let’s start with the basics: what does it mean for something to have “square feet” of area? To measure the size of an object in terms of its area (also called surface area), we multiply its length by its width. This gives us a number that indicates how much space something takes up—or in mathematical terms, the number of square feet or meters or yards (depending on which measurement system you’re using) that are contained within an object’s boundary.

Calculating Watts Per Square Foot

To calculate the watts per square foot for your lighting, use the following formula:

Watts per square foot = watts per bulb x number of bulbs x square footage / 1000

For example, if you have 4 60-watt light bulbs in your space and it measures 30’x30′, then your wattage is equal to:

(60 watts/bulb) x (4 bulbs) x (30’x30′) / 1000 = 1.8 kilowatts.

You need to know how much energy the lights will use and how it will impact your electricity bills.

Energy costs are rising, and lighting is a major source of energy use in most homes. Lighting can be a significant part of your electric bill, so it’s important to understand the difference between watts per square foot (lumens per square foot) and watts per bulb (lumens per bulb).

To calculate lighting energy use, multiply the number of watts by the number of hours you expect to keep them on:

Watts x Hours = Kilowatt-hours/year

The amount of watts per square foot of your building is very important, based on the lighting needs you have. Without knowing what they are, it’s impossible to know how much energy your lights are using or how much money you could save by switching to LED lights. Additionally, if you don’t know the type of lightbulbs you have, then it may be time for a change!
